Experimental Data Acquisition and Processing System Based on Raspberry Pi—Taking RC Transient Circuit as an Example
In the traditional experiment teaching,some experiment measurement data is large and manual process-ing is tedious.In order to improve experimental quality and efficiency,automatic data acquisition and rapid process-ing concept are introduced.Taking the RC transient circuit as an example,an experimental hardware platform was built based on Raspberry Pie and the A/D converter,and experimental data transmission and processing software was developed with Python to achieve automatic experimental data acquisition and rapid processing,and automati-cally generate fitting curves,so as to assist students interpret the experimental results.Practical application shows that the platform enriches the experimental teaching,cultivates the students'independent learning and practical ability,and helps improve the teaching quality of college physics experiments.
